If you can afford it I say get the SL55 more money but wow!

I would love to have an SL55 and a viper if I had the $$$.
I drove an sl500 and loved it, I did not beat it as It was not mine...but dam it was nice. I can only imagine how fast and responsive the sl 55 is.
I have driven the slk line too but not the 55 just the 3.2 amg(like the srt) It was a blast.
I got the limited crossfire due to price 23k out the door new back when they were giving cars away.
I believe the slk is lighter than the sl so the slk could be more nimble...Oh hell get all three and let us know what you think.
